Description: A ransomware attack targeted Collins Aerospace’s **ARINC cMUSE software**, a critical system used by airlines to manage shared check-in desks and boarding gates at major European airports, including **London Heathrow, Brussels, and Berlin**. The attack—identified as a variant of **Hardbit ransomware**—caused **severe operational disruptions**, forcing airlines to revert to manual passenger processing. Recovery efforts were hampered by **repeated reinfections**, prolonging downtime. While no data breach was explicitly confirmed, the incident disrupted **flight operations, airline workflows, and customer experiences**, with lingering effects on check-in systems even after partial restoration. The attack’s **supply-chain nature** amplified its impact, affecting multiple airlines and airports simultaneously. Authorities, including the **UK’s National Crime Agency (NCA)**, arrested a suspect in the UK, but the investigation remains ongoing. The parent company, **RTX**, engaged cybersecurity experts and law enforcement, emphasizing the attack’s **global and persistent threat** to critical infrastructure.

Title: Ransomware Attack on Collins Aerospace Disrupts Major European Airports
Description: A ransomware attack on Collins Aerospace's ARINC cMUSE software caused significant disruption at London Heathrow, Brussels, and Berlin airports, forcing airlines to manually check in passengers. The attack was identified as a variant of the Hardbit ransomware. A suspect in his 40s was arrested in West Sussex, UK, under suspicion of Computer Misuse Act offences. The investigation is ongoing, with speculation about potential nation-state involvement (e.g., Russia), though the arrest suggests a domestic actor. RTX (parent company of Collins Aerospace) is coordinating with cybersecurity experts, law enforcement, and affected stakeholders to mitigate the incident. Most flights have resumed normal operations, though some manual check-ins persist.

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.
Neuron is a PHP framework for creating and orchestrating AI Agents. In versions 2.8.11 and below, the MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions. This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions). Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges are impacted. This issue is fixed in version 2.8.12.
Neuron is a PHP framework for creating and orchestrating AI Agents. Versions 2.8.11 and below use MySQLSelectTool, which is vulnerable to Read-Only Bypass. MySQLSelectTool is intended to be a read-only SQL tool (e.g., for LLM agent querying, however, validation based on the first keyword (e.g., SELECT) and a forbidden-keyword list does not block file-writing constructs such as INTO OUTFILE / INTO DUMPFILE. As a result, an attacker who can influence the tool input (e.g., via prompt injection through a public agent endpoint) may write arbitrary files to the DB server if the MySQL/MariaDB account has the FILE privilege and server configuration permits writes to a useful location (e.g., a web-accessible directory). This issue is fixed in version 2.8.12.
Okta Java Management SDK facilitates interactions with the Okta management API. In versions 11.0.0 through 20.0.0, race conditions may arise from concurrent requests using the ApiClient class. This could cause a status code or response header from one request’s response to influence another request’s response. This issue is fixed in version 20.0.1.
The Auth0 Next.js SDK is a library for implementing user authentication in Next.js applications. When using versions 4.11.0 through 4.11.2 and 4.12.0, simultaneous requests on the same client may result in improper lookups in the TokenRequestCache for the request results. This issue is fixed in versions 4.11.2 and 4.12.1.
